KITCHENER, ON, March 19, 2026 /PRNewswire/ — Canadian Solar Inc. (“Canadian Solar” or the “Company”) (NASDAQ: CSIQ) today announced financial results for the fourth quarter and full year ended December 31, 2025.

Full Year 2025 Highlights

• 24.3 GW of solar module shipments delivered globally, with record 8.1 GW delivered to the U.S. market.
• Record 7.8 GWh of energy storage shipments delivered globally, with 3.9 GWh delivered to the U.S. market.
• Energy storage contracted backlog increased to record $3.6 billion, as of March 13, 2026.
• Completed a US$230 million convertible bond issuance to accelerate U.S. manufacturing initiatives.
• Resumed direct oversight of U.S. operations, forming CS PowerTech as the new U.S. manufacturing platform.
• Fully ramped up Texas module factory to an annual production run rate exceeding 5 GW, with planned expansion to nameplate capacity of 10 GWp by the second half of 2026.

Dr. Shawn Qu, Chairman and CEO, commented, “We demonstrated strategic resilience and operational discipline throughout a year defined by persistent market headwinds and a shifting regulatory landscape. In response to the prolonged solar downturn, we pivoted away from the industry’s traditional focus on shipment volumes and instead took the lead by prioritizing margins and diversifying our profit drivers, notably energy storage. Our commitment to the U.S. market remains steadfast as we spearhead the reshoring of manufacturing to North America. Our solar module factory in Mesquite, Texas has fully ramped up, and we intend to double its nameplate capacity to support a more resilient domestic supply chain. We are moving in the equipment for the first phase of our solar cell plant in Jeffersonville, Indiana as we speak and expect to see the first cell come off the production line by the end of March, with full ramp up expected by the end of June. Furthermore, we are advancing the second phase, which once operational, will bring our U.S. cell capacity to 6.3 GWp, establishing the largest crystalline silicon technology footprint in the country.”

Colin Parkin, President of Canadian Solar and President of e-STORAGE, said, “We shipped 4.3 GW of solar modules this quarter, as we maintained our disciplined approach to order intake amid rising input costs, concluding the year with total shipments of 24.3 GW. Although site construction delays shifted certain energy storage volumes into the first quarter of 2026, we still delivered a record 7.8 GWh in global energy storage shipments. This represents robust double-digit growth, achieved while successfully navigating a turbulent policy environment. Our momentum is further evidenced by a record contracted backlog of $3.6 billion. As we direct our resources toward our comprehensive U.S. manufacturing strategy, we are proactively rebalancing our project development investments to optimize cash flow and manage leverage.”

Ismael Guerrero, CEO of Canadian Solar’s subsidiary Recurrent Energy, said, “Our quarterly revenue and margin profiles were impacted by delays in certain project sales, which have been pushed into 2026. We continue to shift our business mix toward the monetization of operating and under-construction assets to strengthen our balance sheet and improve cash flow. As we manage the pacing of construction activities, we are also optimizing our pipeline for quality, focusing on generating value from existing opportunities.”

Xinbo Zhu, Senior VP and CFO, added, “For the fourth quarter, we reported revenue of $1.2 billion and a gross margin of 10.2%. Profitability was affected by sequentially lower global storage volumes and solar module deliveries to the North American market, delayed project sales, and project asset impairments. Capital expenditures in 2025 totaled $962 million, slightly below expectations, and we ended the year with a cash position of $1.9 billion.”

Fourth Quarter 2025 Results

Total solar module shipments recognized as revenues in Q4 2025 were 4.3 GW, down 16% quarter-over-quarter (“qoq”) and down 47% year-over-year (“yoy”).

Net revenues were $1.2 billion in Q4 2025, down 18% sequentially and 20% yoy, mainly due to lower sales of solar modules and battery energy storage systems.

Gross profit was $124 million, compared to $256 million in Q3 2025 and $217 million in Q4 2024. Gross margin was 10.2%, compared to 17.2% and 14.3% in Q3 2025 and Q4 2024, respectively. The sequential decrease in gross margin was primarily due to the impairment charges related to certain project assets. The yoy decrease was driven by lower contribution from solar modules and project asset sales, partially offset by higher module ASPs.

Operating expenses were $188 million, down from $222 million in Q3 2025 and $344 million in Q4 2024 due to lower logistics costs. Operating expenses represented 15.5% of revenue, compared to 14.9% in Q3 2025 and 22.6% in Q4 2024.

Net loss attributable to Canadian Solar in accordance with generally accepted accounting principles in the United States of America (“GAAP”) in Q4 2025 was $86 million, or a net loss of $1.66 per diluted share, compared to a net income of $9 million, or a net loss of $0.07 per diluted share, in the Q3 2025, and net income of $34 million, or $0.48 per diluted share, in Q4 2024. Net income/(loss) per diluted share includes the dilutive effect of convertible bonds, as applicable, and the Recurrent Energy redeemable preferred shares dividends.

Net cash flow used in operating activities in Q4 2025 was $65 million, driven by changes in working capital, specifically an increase in project assets, partially offset by a decrease in inventories, compared to net cash flow used in operating activities of $112 million in Q3 2025 and net cash flow provided by operating activities of $66 million in Q4 2024.

Total debt, including financing liabilities, was $6.5 billion as of December 31, 2025, including $3.8 billion, $2.5 billion and $0.2 billion related to Recurrent Energy, Manufacturing, and convertible notes, respectively. Total debt increased from $6.4 billion as of September 30, 2025, mainly due to new borrowings for construction of projects. Total non-recourse debt under Recurrent Energy as of December 31, 2025, was $2.2 billion.

Business Segments

On December 1, 2025, Canadian Solar announced a strategic initiative to resume direct oversight of its U.S. operations. The Company has formed a new joint venture with its majority-owned subsidiary, CSI Solar Co., Ltd. (“CSI Solar”), by holding a 75.1% controlling stake in CS PowerTech Inc. (“CS PowerTech”), which operates U.S.-based manufacturing and sales of solar modules, solar cells, and advanced energy storage systems. On December 16, 2025, CSI Solar’s shareholders approved the proposed initiative.

Following the consummation of this strategic initiative, Canadian Solar’s business is organized into two segments:

• Manufacturing, comprising CS PowerTech, which focuses on manufacturing and sales of solar modules, battery energy storage products, and other power technology products for the U.S. market, and CSI Solar, which serves all other global markets; and
• Recurrent Energy, which focuses on solar power and battery storage project development, asset sales, power services, and electricity revenue from its operating portfolio.

Manufacturing

Solar Modules and Solar System Kits

The Company shipped 4.3 GW of solar modules and solar system kits to more than 70 countries and regions in Q4 2025.

Consistent with the Company’s transition from volume-driven growth to high-value creation, the Company will focus its disclosure on strategic markets rather than aggregate global manufacturing capacity.

In the U.S., the Company operates a 5 GWp solar module factory in Mesquite, Texas, which will be expanded to nameplate capacity of 10 GWp by the second half of 2026.

The Company is also continuing to advance its flagship, state-of-the-art heterojunction technology (“HJT”) solar cell factory in Jeffersonville, Indiana. In response to strong customer demand, the Company is increasing its production capacity beyond 5 GWp, with additional production lines being installed and commissioned through 2026.

• Phase I: Trial production is scheduled to begin by April 2026. Phase I has a nameplate capacity of 2.1 GWp and represents the only commercially operational HJT solar cell facility in the U.S.
• Phase II: The Company expects to begin trial production for Phase II by the end of 2026. This expansion will add 4.2 GWp of capacity, bringing the Company’s total solar cell nameplate capacity in the U.S. to 6.3 GWp.

e-STORAGE: Battery Energy Storage Solutions

As of March 13, 2026, e-STORAGE contracted backlog, including contracted long-term service agreements, stood at $3.6 billion. These signed orders carry contractual obligations to customers and provide significant earnings visibility over a multi-year period.

Recurrent Energy

As of December 31, 2025, the Company had a total global solar project development pipeline of approximately 24 GWp and a battery energy storage project development pipeline of 83 GWh.

The business model consists of three key drivers:

• Electricity revenue from operating portfolio to drive stable, diversified cash flows in growth markets with stable currencies;
• Asset sales, including selective operating assets in stable currency markets and assets in the rest of the world, to manage cash flow, debt level and to fund growth in operating portfolio; and
• Power services (O&M) through long-term operations and maintenance (“O&M”) contracts, currently with nearly 15 GW of contracted projects, to drive stable and long-term recurring earnings and synergies with the project development platform.

Project Development Pipeline – Solar

As of December 31, 2025, the Company’s total solar project development pipeline was 24.4 GWp, including 1.6 GWp under construction, 3.2 GWp of backlog, and 19.6 GWp of projects in advanced and early-stage development, defined as follows:

• Backlog projects are late-stage projects that have passed their risk cliff date and are expected to start construction within the next one to four years. A project’s risk cliff date is the date on which it passes the last high-risk development stage and varies by country. Typically, this occurs after the project has received all required environmental and regulatory approvals, and entered into interconnection agreements and offtake contracts, including feed-in tariff (“FIT”) arrangements and power purchase agreements (“PPAs”). A significant majority of backlog projects are contracted (i.e., have secured a PPA or FIT), and the remainder have a reasonable assurance of securing PPAs.
• Advanced pipeline projects are mid-stage projects that have secured or are more than 90% likely to secure an interconnection agreement.
• Early-stage pipeline projects are early-stage projects controlled by the Company that are in the process of securing interconnection.

While the magnitude of the Company’s project development pipeline is an important indicator of potential increases in power generation and battery energy storage capacity, as well as potential future revenue growth, the development of projects in its pipeline is inherently uncertain. If the Company does not successfully complete the pipeline projects in a timely manner, it may not realize the anticipated benefits of those projects to the extent expected, which could adversely affect its business, results of operations, and financial condition. In addition, the Company’s guidance and estimates of its future operating and financial results assume the completion of certain solar projects and battery energy storage projects in its pipeline. If the Company is unable to execute on its actionable pipeline, it may fail to meet its guidance, which could adversely affect the market price of its common shares and its business, results of operations, and financial condition.

The following table presents the Company’s total solar project development pipeline.

 

Project Development Pipeline – Battery Energy Storage

As of December 31, 2025, the Company’s total battery energy storage project development pipeline was 83.5 GWh, including 6.2 GWh under construction and in backlog, and 77.3 GWh of projects in advanced and early-stage development.

The table below sets forth the Company’s total battery energy storage project development pipeline.

 

Business Outlook

The Company’s business outlook is based on management’s current views and estimates given factors such as existing market conditions, order book, production capacity, input material prices, foreign exchange fluctuations, the anticipated timing of project sales, and the global economic environment. This outlook is subject to uncertainty with respect to, among other things, customer demand, project construction and sale schedules, product sales prices and costs, supply chain constraints, and geopolitical conflicts. Management’s views and estimates are subject to change without notice.

In Q1 2026, the Company expects total revenue to be in the range of $900 million to $1.1 billion. Gross margin is expected to be between 13% and 15%. Total module shipments recognized as revenues are expected to be in the range of 2.2 GW to 2.4 GW. Total battery energy storage shipments in Q1 2026 are expected to be in the range of 1.7 GWh to 1.9 GWh.

The Company is issuing new guidance of 6.5 to 7.0 GW of solar modules and 4.5 to 5.5 GWh of battery energy storage solutions to the U.S. in 2026.

Dr. Shawn Qu, Chairman and CEO, commented, “While the first quarter tends to be seasonally softer, we are navigating a complex macro environment, including elevated and volatile input costs across supply chains and policy uncertainty in key markets. In our project development business, we are rebalancing toward asset monetization and optimizing our cost structure. Our solar module shipments in the U.S. are expected to be slightly lower in 2026 than in 2025, primarily due to a limited supply of solar cells qualified as non-PFE under the OBBBA in the first half of the year. The high cost of such cells will also affect our profitability. I believe this is temporary, as our own production will ramp up in Q2 and Q3. 2026 will be a transition year, as we accelerate our U.S. manufacturing roadmap and diversify our long-term profitability drivers.”
